Chadwin House is a low-rise apartment building, now condominiums. It was built in 1963 to designs by prolific architect Horace Ginsbern, most well-known for his deco-style apartment buildings on the Grand Concourse in the Bronx. He was still designing until his death in 1969 and his son carried on the firm until at least the 1980s.
The bands of white brick on Chadwin House contribute to its horizontality and also enliven a fairly utilitarian facade. Columbia University has a sales brochure of Chadwin House that makes it seem like the building was trying to fit in well with its older Chelsea neighbors. The brochure also shows a simpler, curved mid-century entrance canopy and a decorative metal screen on the windows to the left of the entrance.
With much new construction going on in Chelsea, this block of Seventh Avenue is a low-rise anomaly given the Chadwin House’s placement directly across Seventh Avenue from a one-story power station.
